The dollar gained on Thursday as rising geopolitical tensions provided a safe haven boost to the currency, while the British pound fell after the Bank of England cut interest rates from a 16-year high.

Concerns about a widening conflict in the Middle East intensified this week after Hamas leader Ismail Haniyeh was assassinated in the Iranian capital Tehran on Wednesday morning, an attack that drew threats of revenge on Israel.

"We are looking at the threat of outright conflict breaking out in the Middle East," said Karl Schamotta, chief market strategist at Corpay in Toronto. "That is supporting the dollar's safe haven appeal."

The dollar also bounced as a selloff on Wednesday following dovish comments by Federal Reserve Chair Jerome Powell at the conclusion of the U.S. central bank's two-day meeting was seen as possibly overdone.

"Although Jerome Powell was extremely dovish in the press conference, the statement released by the Federal Open Market Committee really sounded more balanced," said Schamotta.

Powell said that interest rates could be cut as soon as September if the U.S. economy follows its expected path, after the Fed's new policy statement noted that "there has been some further progress toward the (Federal Open Market) Committee's 2% objective," while the unemployment rate, at 4.1%, "remains low."

Traders are now pricing in three 25-basis-point rate cuts by year-end, indicating one cut at each of the Fed's September, November and December meetings.

The next major U.S. economic release that is likely to drive Fed policy will be Friday’s government jobs report for July. It is expected to show that employers added 175,000 jobs during the month, while the unemployment rate is expected to stay steady at 4.1%.

The dollar index was last up 0.06% at 104.11.

Data on Thursday showed that the number of Americans filing new applications for unemployment benefits increased to an 11-month high last week.

Sterling slipped 0.18% to $1.2833 after the Bank of England cut interest rates following a tight vote by its policymakers who were split over whether inflation pressures had eased sufficiently.

Governor Andrew Bailey led the 5-4 decision to reduce rates by a quarter-point to 5% and he said the BoE would move cautiously going forward.

"If you look at the headlines that Bailey produced: caution on cutting too quickly or by too much, it implies to me that they're looking at a sort of a steady quarterly pace of reductions," said Colin Asher, economist at Mizuho.

The euro touched a three-week low of $1.07775 and was last down 0.11% at $1.0813.

The Japanese yen dipped, a day after a dramatic rally following the Bank of Japan’s decision to hike rates to 0.25%, the highest since 2008.

The yen has gained since hitting a 38-year low of 161.96 against the dollar on July 3, boosted by interventions by Japanese authorities and traders unwinding carry trades in which they were short the yen and long U.S. dollar assets.

The dollar was last up 0.11% at 150.15.

In cryptocurrencies, bitcoin gained 0.03% to $64,584.
